This invention relates generally to liniprovements in the construction of and method of forming'paper bags and particularly inrconnection with bags adapted rto be used as protective wrappers for .large bunches of bananas on the stalk. 4 f It'has' been a principal object of the invention yto simplifyiand reduce the cost of the constructionJr of bags of the type mentioned and atthe same time to increase the strength ofthe same so -that they will readily withstand vthel strains toy which they may be subjected.y Heretofore it has Y been the practice to employ, in the shipment of large bunches of lbananas,"bags which have the .usual glued or pasted seam construction at the bottom with; an opening merely cut at the center thereof to permit the end of the/stalk to extendthrough the bott-om of the bag. The opposite or open end of the bag is then usually; gathered together. and tied with a piece of twine or the like.

According to the present invention it is proposed to produce a bag from a tubular paper member formed .with a longitudinal seam, preferably glued or otherwise cemented. The bottom ,of the bag will preferably, although not necessarily, be reinforced and will be closed by suitable Vmechanical fastening means which may be so located as to leave This type of construction readily permits a large central opening of the` desired size.

forming themain body. of the bag in long continuous strips which are subsequently cut into sections.` Y Y VWith these and other objects and advantages in view, the invention will now be described lby reference tothe accompanyingV "h'l l'd'rbl., drawlngs whlc disc ose severa a mi a el'14 and l5 and the top layer 16. At the mid- F igure'2 is adetail view showing one form v offastening and reinforcing means employed i at the closed endof the bag.l

Figure 9 is an enlarged sectional viewV taekn along the line 9 9 of Figure 7.

Referring now to Figures 1 to 5, inclusive, which 'disclose one desirable form of the invention, the bag may be constructed of a sheetof paper of any suitable weight and texture formed into a tubular member 10 having a longitudinal seam 11. This seam may be glued, pastedy or cemented by any vsuitable adhesive medium or it may be formed bythe use of any desired type of mechanical fastening means. If the main body of the bag is formed of waxed or oiled paper for the purpose of excluding moisture as far as possible, it will be preferable to omit the oil or..

' which may be produced in any suitable way,

with its side portions folded inwardly'7 to a point indicated by the broken lines 12 in F ig ure` 12 l This will result in a four-layer construction at the edges of the strip, including the bottom vlaver 13, the intermediate 'layers portions of the bag between the fold lines 12 there will be only the two thicknesses of paper 18 and 16, which will constitute" the opposite mainV walls of the bag.

Now, in order to partially close one end of the bag, the layers 13 and l14 of the paper on the one hand kandthe layers 15 and 16 on the'other hand may be suitably folded around and enclose appropriate reinforcing velevments. For example, the material forming the layers 18 and 14; may be folded around- 39' vper fastening device 25, havingy a largehead "7"*55 'isformed is tough and durable, the reinforce.-

a reinforcing cord' or string 17 and may `eX- tend downwardly, as indicated by the piortions 18 and 19 in Figure 5, to any suitable extentand may then be bent inwardly and upwardly into folds 20 and 21 which tenmi-y f suitably tied together to retain them` finlp'lace.

j A nysuitable fastening means vmay rbe `,provided across Vthe bottom'of the bag l for securing .the foldsV in the positions Vindicated and"v to close lthe bag 4to f any extent desired.
